Description

発明の詳細な説明Detailed Description of the Invention

本発明は、水位の変化により上下に可動可能な水中膜に関する。  The present invention relates to an underwater film that is movable up and down by a change in water level.

従来、ポンプ所・取水口・沈砂池等に展張されている水位の変化により上下に可動するオイルフェンス１等は、オイルフェンスの上部近傍にリング２を設け、このリングを護岸等に設けられたガイドポール３に挿通して設置されていた（図１参照）。また他の方法として護岸等に設けられた中空管４を用い、該中空管に垂直にスリット状の切り欠き部５を設け、該中空管内を摺動可能なフロート状金具６をオイルフェンス１の両端部に設けた装置が知られている（図２参照）。
さらに、水中膜の上部近傍部の両端部に、水中膜に対してそれぞれ直角方向（二方向）にアームを設け、該アームに補助フロートを設け、かつ前記水中膜の上部近傍部の両端部にリングを設け、該リングを、ガイドポールに挿通し、該ガイドポールを護岸等に固定してなる装置が知られている。
しかしながら図１のような装置はリングの重みで長時間の間に水平位置が保たれずに垂れさがった状態になり、また水流により水中膜が傾斜することによってリングが斜めになることからガイドポールとの間に摩擦力が増大して結果的にリングがガイドポールに引っかかる状態となり、水位の変化によって水中膜が上下に可動することが不可能となる欠点があった。
また、図２のような装置はフロート状金具６の浮力を増す方法として、フロート状金具６を長くすることや径を大きくすることが上げられるが、フロート状金具６を長くすると金具の重量が大きくなり、その結果、浮力の増加が小さいことや、該中空管４内のフロート状金具６がつかえる状態となり、水位の変化によって水中膜が上下に可動することが不可能となる。フロート状金具６の径を大きくすると浮力は増加するが、該中空管４の径も大きくなり、高価格になる欠点があった。Conventionally, an oil fence 1 etc. that can move up and down due to changes in the water level that has been extended to pump stations, water intakes, sand basins, etc. has been provided with a ring 2 near the top of the oil fence, and this ring has been provided on a seawall etc. It was installed through the guide pole 3 (see FIG. 1). As another method, a hollow pipe 4 provided on a revetment or the like is used, a slit-like cutout portion 5 is provided perpendicularly to the hollow pipe, and a float-like metal fitting 6 slidable in the hollow pipe is provided as an oil fence. 1 is known (see FIG. 2).
Furthermore, an arm is provided at both ends of the vicinity of the upper portion of the underwater membrane in a direction perpendicular to the underwater membrane (two directions), an auxiliary float is provided on the arm, and both ends of the upper vicinity of the underwater membrane are provided. There is known an apparatus in which a ring is provided, the ring is inserted into a guide pole, and the guide pole is fixed to a revetment or the like.
However, the device as shown in FIG. 1 is in a state where the horizontal position is not maintained for a long time due to the weight of the ring, and the ring is inclined due to the inclination of the underwater film due to the water flow. As a result, the frictional force increases and as a result, the ring is caught on the guide pole, and the underwater film cannot be moved up and down due to the change in the water level.
Further, in the apparatus as shown in FIG. 2, as a method of increasing the buoyancy of the float metal fitting 6, it is possible to increase the length of the float metal fitting 6 or increase the diameter. As a result, the increase in buoyancy is small, and the float-like metal fitting 6 in the hollow tube 4 can be used, and the underwater film cannot be moved up and down due to the change in the water level. When the diameter of the float metal fitting 6 is increased, the buoyancy is increased, but the diameter of the hollow tube 4 is also increased, resulting in a high price.

そこで本発明者は、急激な水位上昇によっても水中膜に設けられたリングがガイドポールに引っかからず、水中膜が上下にスムーズに可動する水中膜について種々研究を重ねた結果本発明を完成するに至った。  Therefore, the present inventor has completed various studies on the underwater film in which the ring provided in the underwater film is not caught by the guide pole even when the water level is suddenly increased and the underwater film moves smoothly up and down. It came.

すなわち、本発明は、水中膜の上部近傍部の両端部に、水中膜に対してそれぞれ直角方向にアームを設け、該アームに補助フロートを設け、かつ前記水中膜の上部近傍部の両端部にリングを設け、該リングをガイドポールに挿通し、さらに該リングの下部に補助ブイをガイドポールに挿通して設け、前記ガイドポールを壁面等に固定してなる、水位の変化によって上下に可動可能な水中膜である。  That is, the present invention provides an arm in the direction perpendicular to the underwater film at both ends near the upper part of the underwater film, an auxiliary float on the arm, and both ends near the upper part of the underwater film. A ring is provided, the ring is inserted through the guide pole, and an auxiliary buoy is inserted through the guide pole at the bottom of the ring. The guide pole is fixed to the wall, etc. It is an underwater film.

本発明方法によれば、水中膜は急激な水位上昇、また上下可動する場合にガイドポール３にリング１８が引っかかることもなく水位の変化に応じてスムーズに上下動を行うことができる。
また使用する補助ブイは、既設のガイドポール等を改良することなく設置が可能で、補助ブイも安価である。According to the method of the present invention, the underwater film can move up and down smoothly in response to a change in the water level without a ring 18 being caught by the guide pole 3 when the water level rapidly rises and moves up and down.
The auxiliary buoy to be used can be installed without improving the existing guide pole and the like, and the auxiliary buoy is also inexpensive.

発明の実施するための最良の形態BEST MODE FOR CARRYING OUT THE INVENTION

次に本発明をさらに詳細に説明するために図面を参照しながら説明するが、本発明は以下の説明のみに限定されるものではない。  Next, the present invention will be described in more detail with reference to the drawings. However, the present invention is not limited to the following description.

図３Ｂは、本発明に係る水中膜の一部を切り欠いた端部部分の側面図を示す。本発明の水中膜７は多数のフロート８をテンションゴムベルト９で挾着してフロート部１０を構成し、このフロート部１０の下部にカーテン１１を一体に設ける。フロート部１０の両端部（図３は左側部のみ）には取付金具１２によって該フロート部を挾持するように設ける。
フロート部１０に補助フロート体１３を設ける。このフロート体１３は、中心部にパイプ挿通口１４を有し、そこにパイプ１５を挿入する。このように構成したパイプ１５の上、下端をＬ字状のアーム１６の一端の直線部に一体に設け、そのＬ字状のアーム１６の他端の屈曲部をテンションベルト９に例えばボルトナットで一体に設ける。FIG. 3B shows a side view of an end portion in which a part of the underwater membrane according to the present invention is cut away. In the underwater membrane 7 of the present invention, a large number of floats 8 are attached by tension rubber belts 9 to form a float portion 10, and a curtain 11 is integrally provided below the float portion 10. At both ends of the float portion 10 (only the left side in FIG. 3), the float portion is provided so as to be held by the mounting bracket 12.
An auxiliary float body 13 is provided in the float unit 10. This float body 13 has a pipe insertion opening 14 at the center, and a pipe 15 is inserted therein. The upper and lower ends of the pipe 15 configured in this way are integrally provided on the straight portion of one end of the L-shaped arm 16, and the bent portion of the other end of the L-shaped arm 16 is attached to the tension belt 9 with, for example, a bolt nut. Provide one.

本発明の水中膜はその両端部の取付金具１２にシャックル１７を設け、このシャックル１７にリング１８を設け、このリング１８の下部に補助ブイ１９をガイドポール３に挿通して設ける。このように設けることによって補助ブイ１９が常にリング１８を水平状態で押し上げ、リング１８の垂れ下がりを防止する。  In the underwater membrane of the present invention, shackles 17 are provided on the mounting brackets 12 at both ends thereof, a ring 18 is provided on the shackle 17, and an auxiliary buoy 19 is inserted through the guide pole 3 below the ring 18. By providing in this way, the auxiliary buoy 19 always pushes up the ring 18 in a horizontal state and prevents the ring 18 from hanging down.

本発明の水中膜はリング１８の下部に補助ブイ１９を設けることによって、リング１８を水平に保ちガイドポール３とリング１８との間の摩擦力を減らし、結果的にリング１８がガイドポール３に引っかからずに、急激な水位上昇においても可動可能な水中膜とすることができる。  In the underwater membrane of the present invention, the auxiliary buoy 19 is provided at the lower part of the ring 18 to keep the ring 18 horizontal and reduce the frictional force between the guide pole 3 and the ring 18. Without being caught, it is possible to provide a movable underwater film even in a sudden rise in water level.

本発明の水中膜はシャックル１７を鎖２１によって取付金具１２に連結することによってシャックル１７の上下の変動を制御することができる。  The underwater membrane of the present invention can control the vertical fluctuation of the shackle 17 by connecting the shackle 17 to the mounting bracket 12 by the chain 21.

本発明の水中膜は水面上の浮遊物を岸壁と水中膜の隙間からの流出を防止するために例えば移流フィン２２を岸壁等に設ける。
尚、この移流フィン２２は、水中膜７のフロート８の一部と常に接している構造で、硬質性のゴムと軟質性のゴムを組み合わせたものが良い。The underwater film of the present invention is provided with, for example, advection fins 22 on the quay or the like in order to prevent the floating matter on the water surface from flowing out from the gap between the quay and the underwater film.
The advection fin 22 has a structure that is always in contact with a part of the float 8 of the underwater film 7, and a combination of hard rubber and soft rubber is preferable.

図３Ｂでは補助ブイ１９を１個装着する場合を示したが、複数個を多段に装着することもできる。これらの補助ブイ１９は球状、楕円状、円筒状それぞれ異なる形状のものも使用することができる。  Although FIG. 3B shows a case where one auxiliary buoy 19 is attached, a plurality of auxiliary buoys 19 can be attached in multiple stages. These auxiliary buoys 19 can be spherical, elliptical, or cylindrical, and can have different shapes.

図４では補助ブイ１９は、護岸等に設けられた該中空管４内を摺動可能なフロート状金具６を挿入し、フロート状金具６の下部に置くこともできる。フロート状金具６の下部に補助ブイ１９置くことでフロート状金具６の重量を増すことなく、浮力だけを増加することができ、既設の設備を変えることなく、安価に改良できる。
尚、取付金具１２に補助フロート体１３を設けてもよい。In FIG. 4, the auxiliary buoy 19 can be placed under the float metal fitting 6 by inserting a float metal fitting 6 slidable in the hollow tube 4 provided on the seawall or the like. By placing the auxiliary buoy 19 under the float-shaped metal fitting 6, only the buoyancy can be increased without increasing the weight of the float-shaped metal fitting 6, and it can be improved at low cost without changing the existing equipment.
An auxiliary float body 13 may be provided on the mounting bracket 12.

図５では護岸等に移流フィン２２を設け、水面上の浮遊物が該中空管４と摺動可能なフロート状金具６の隙間に入り込みを防止することで、水位の変化によって水中膜が上下に可動することとなる。
また、オイルフェンス１に補助フロート体１３を設けてもよい。In FIG. 5, advection fins 22 are provided on the revetment, etc., and suspended matter on the water surface is prevented from entering the gap between the hollow pipe 4 and the slidable float 6 so that the submerged membrane moves up and down due to the change in water level.
